my team is moving to a new league in NY and the jerseys mandate the "fight strap". Were can I get these? or can i have them sent to me?

That is a toughie. They actually mandate fight straps? Quick internet search revealed nothing in terms of making/buying one. I would guess go to a really good hockey supply store and see if they have any suggestions. Where in NY are you playing?

That's super weird that they'd require fight straps. Fight straps are essentially there so that no-one can pull their jersey off easily during, well, during a fight. Most Rec Leagues in the the US play by USA Hockey rules, and fighting is strictly forbidden. I know in my league you receive a $50 fine and you're tossed for the session.
